G920I 5.1.1 OJ6 Unable to flash eng Sboot.bin

---

Hello,

I have a S6 G920I on 5.1.1. I rooted before i completed the IMEI repair. had to backup the cert.

I have the Factory binary: COMBINATION_XSA_FA50_G920IDVU2AOL1_XSA2AOL1_CL6411 720_QB7437590_REV02_user_mid_noship.tar.md5

however, everytime i tried to flash the eng sboot.bin from the above binary, i get this error:

sw rev. check fail device:3 Binary: 2

This error typically shows when we try to downgrade, but in this case, my stock was OJ6, and I'm flashing OL1 ... factory binary is newer.

I'm able to flash G920IDVU3DOL5_G920IODD3DOL1_G920IDVU3DOL5_HOME

then flash back to G920IDVU3DOJ6_G920IXSA3DOJ6_XSA

just cannot load the eng sboot so i can write the cert.

GCPro software says Custom kernel can allow me to write cert on a rooted phone as well? anyone know which kernel i can use to accomplish this?

Thanks.
